"These bulletins differ from recalls in that they are not considered safety or emissions issues and they usually apply only when your vehicle is in its warranty period (whereas a recall is "open" until the work has been performed). TSBs frequently (but not always) address a recurring problem and include illustrated instructions for repair, a list of the parts needed, the warranty status and the labor charge."
How Can a Technical Service Bulletin Help Me?
Anyways, before I get upset again, I was drving down the road yesterday on the interstate. I was going about 77mph I think, and all of the sudden the car jerked forward slightly and I soon realized the engine was not running. All sustems appeared on, but I dont recall it the radio stayed on cause I was talking on the phone and had the volume down. But then the MSG indicator came up saying something about "Service Brakes" or "Check Break system". All still rolling along at 75 MPH with no power. And the Radio went from the Pearl Jam Channel on XM to the ELvis Channel... So I pulled the hazards and started to creep off the road, but quickly realized I could start in neutral so moved to neutral and cranked it uppulled it back down in drive (still going 55) and just hit he gas and went.
That was the first problem I have ever had with mine that was significant.
Yes these cars are having serious issues. My Wife's 2003 has had electrical problems it entire like and I am starting to think it has to do with door switch failures or malfunctions. NOT HAPPY ///

**** I am trouble shooting why my "Rear Hatch" switch doesn't work.
I have power to the "Rear Hatch" switch. I removed the actuator from the rear cargo door and jumpered it to the battery. It actuates each time I touch the battery terminals. I am not getting voltage to the actuator when the switch is depressed. (I have two extra switch I bought from a local junk yard - AC Delco doesn't make these any more.) I purchased a Chiltons manual from a local auto parts store. The wiring diagram is very basic.
The power is supplied from a "DR LOCK FUSE 20A" which is hot at all times. This is located in the - Left Bussed Electrical Center. I looked in the left side fuse panel. There is one 20A fuse which is labeled "CTSY". This fuse has high resitance - 16.5 OHM. The rest of these fuses have average of 0.5 OHM.
The basic electrical diagram mentions a "Right Bussed Electrical Center". I can not find this fuse panel or fuseable links. I need to verify voltage from the left side panel to this location to help trouble shoot my potential short.
Best Regards,
Jason Hampton
My vehicle is currently at the dealership.
The latest intermittent behaviour is:
- Put the key into the ignition and go to start the vehicle.
- Sometimes nothing will power up and you might get one loud click.
- Sometimes the engine lamp illuminates but nothing else powers up.
- Turn the key back to the off position and attempt to start again.
- The vehicle will start on retrying but the clock on the radio would reset.
This has been going on intermittently since about Dec 9th.
This last week around Dec 30th the radio finally died and is no longer functioning.
The dealer says the radio will have to be replaced.
Prior to this, the car was in the shop 3 times over a 3 week period in 2012 for a similar behaviour where intermittently:
- Put the key into the ignition and go to to start the vehicle
- Sometimes nothing will power up and you might get one loud click.
- The battery would be completely drained.
- Apply a jump pack to the vehicle and jump start it.
The vehicle would then start and do so over approximately a week until the battery drained again.
I turns out the vehicle's AC blower motor was engaging while the vehicle was not started, i.e. no key in the ignition. They replaced the blower motor and relay to the blower motor, however the battery drain and failure to start persisted.
The dealership believed that it might be a short in the battery cable but could not definitively prove that. They suggested that if it happened again I should manipulate the cable to see if it would then start and if it did bring it back in. It did not happen again for several months until the the most recent behavior began happening. I have not had to manipulate the battery cable to get the vehicle to start on a second attempt.
There were other issues with door locks and AC vent doors prior to this, all of which seem to be electrical problems. All of this on a vehicle that is about 4 years old with 49,000 miles on it.
So, with the latest issue, where do I even begin? I'm in the shop for repair, but I have little faith that a real root cause will be found.
This is my second Tahoe and I am extremely disappointed with the quality of the vehicle.

-no codes!!
-air bag light is on & controls on steering wheel not working
-As I stated: no codes and the controls on the steering wheel work but are not transmitting past the steering wheel(this was check today at Car Toys)
-Initially thought that the clock spring was bad but the cruise and horn work fine.
-I have looked for wiring diagram for under driver's seat because: 2 orange wires are not connected. Could this be the culpret?
--Any help is appreciated
My 99 is sitting in the drive way dead and we are down to one car between my wife and myself adn I work a half hour from home which makes it hard for her to get our daughter from school. Any details you can off would be most appreciated. I am looking for a lead because I am dumbfounded as to how it could just die with no warning signs.
thanks
I have spoke on the phone with 3 different GM customer relations representatives and they were as much help as the place I purchased my vehicle. How many things, that are the SAME issues, to all these different GM vehicles have to occur before a recall is done and customers get some satisfaction instead of just dishing out money for diagnostics, parts, etc. and nothing is ever fixed. I will never buy another GM product. Worthless!!!!!
Mine is having the same issues while driving, door locks going up and down, gauges moving back and forth, lights flickering, sometimes the tahoe shutters, and this usually happens anywhere from 3-10 seconds. And when this does occur, when I get to my destination and shut off the car, then it always goes completely dead. Then I can hear a intermittent clicking noise coming from the door locks and under the dash, but nothing works at all. I always disconnect/reconnect my battery cables, and it always temporarily solves the problem. This may happen a couple of times a day or it may drive normal for a month or so. I bought the tahoe used in april 2012, and it did this off and on until around oct 2012. Then it ran perfect up for about 6 months, and now yesterday it did it again.
I don't have a ton of money to throw at it, and I usually do all car repairs myself, but this has got me stumped. Any help would be greatly appreciated.
To the Chevy employees watching. Please do not respond and tell me you are happy I have found a fix or that it is great the car is working again. This is not a fix to a problem that is serious and causes all of us grief.
Hope this helps others avoid the dealership or local shop.
Another thing I've noticed is that a lot of us are in Texas, so I was thinking it could be something getting too hot, which could be ground/wire related.
Thanks for the input!
I'm sorry that you have not received a response. We recently made a few changes and Crystal and Jackie are now monitoring this forum. I would be happy to take a look into this for you. Can you send me an email with your full name, and Vehicle Identification number please so I can look up your case and provide you with an update? Look forward to hearing from you:-). My email address is socialmedia@gm.com "attn Crystal" in the subject line.

This morning AS I WAS DRIVING TO WORK, the dash flickered and the "stabilitrak off" sign lit up. A few minutes later, the same thing happened, along with the seat belt sign flashing on as though I was not wearing my belt when in fact I was. Thankfully I made it to work, popped open the hood - keep in mind that I am 6 months pregnant - checked the battery for any leaks, loose connections, etc. and didn't find a thing. I didn't lock all the doors so that I can get in later just in case the thing dies while I'm in the office. Based on what I've read from others on this forum, disconnecting and reconnecting the battery could be a temporary fix. Guess I'll try that during my lunch break....
My husband and I bought this car thinking we'd get a safe auto for our growing family, and so far, that decision has been a big mistake. I haven't even delivered yet, and already have had to call AAA twice in the last six months to help me out bc the dealership doesn't know what the H to do.
I dread to imagine what will happen after my son is finally here in three months and I'm driving with him in the car when the car dies!! Hopefully we won't be trapped inside bc the doors won't unlock!
I obviously concerned for her safety, I drove the vehicle and tried to get the vehicle to do the same for me and it did not. The next day, she took the suv to work and in the middle of an intersection the truck shut down on her, all lights on the dash lit up, the locks flickered, blind side alert msg as well as having a check engine light. While in that intersection she panicked, turned the truck off and started it again to get out of the intersection. She called me and I asked if the check engine light was still on, with her reply, "no." just in case the computer logged it, I had her push the onstar button and had them do a diagnostic on the vehicle not 2 minutes after the occurrence, and for them to tell me nothing was wrong with the tahoe.
The next day, we noticed our dash was cracked and and was going to have that replaced on some dealer warranty funded programmed and I advised them of the problem. The service person looked at me as if I was stupid, mind you I know my way around under a hood pretty well.
After having the new dash installed and picking up my tahoe, the service manager stated, "we found a misfire, we cleared it out and "reprogrammed" the computer". So to me, means they didn't find crap, and he told me that to appease me.
On my way home the tahoe, finally messed up with me in the vehicle. This time at 60mph down the road the truck started to feel rough and shake, the locks flipped on and off, blind side zone alert msg, then the truck hick up, the transmission went bang (like a neutral drop feeling) the check engine light came on, then a half of a second later the truck was running fine. I watched the voltage gauge fluctuate from 10 volts to 18 volts back to 10 then back to 18. Fearing I was going to blow or cook the battery I stopped the vehicle and turned it off. I lifted the hood and saw miner corrosion on the positive lead.
I started the truck back up and found the truck to running normal but I stopped and the nearest O'riely's Auto parts store and picked up a new battery. I got home and replaced the battery and cleaned tightened all leads.
Yesterday the Tahoe still is doing the same thing, its been in the shop 2 times now with nothing fixed. Its the same almost every time. No check engine light.
Symptoms:
+++++++++
truck begins to idle rough or shake depending if you are stopped or traveling.
locks engage then disengage
blind side alert flashes across the instrument cluster
if driving (a pop under the carriage) like a neutral drop
check engine light for 1-2 seconds
the volt gauge fluctuates from 10 to 18 volts
then the truck runs fine.
I have had a Denali, Yukon, and now this Problem Tahoe... not happy!!
There are a bunch of posts with this same problem in this forum. I've read most of them but probably not all. A lot of the folks have done a great deal of maintenance from changing out the battery like you to replacing the whole engine - that's a lot of dollars.
The post that interested me was someone who had read somewhere else about a ground being corroded on the back of the engine. They replaced it and the problem cleared.
I would recommend to you to do a search on this forum and get a feel for the different solutions and non-solutions that people have tried. It's definitely more than just a one-off problem you're having.
Just one guys opinion.
SM
--Engine noise through speakers (all factory radio/Nav)
--Radio power/display will cut on and off while driving and stability trac dash light and check engine light will flash on and off and the same time
--Sometimes the locks will cycle when it goes haywire but that's maybe 20% of the time.
I am working on replacing all my positive and negative cables with new grounds and connections to see if that repairs it. I'm just amazed at how many people are having these issues and there doesn't seem to be any TSB's or any urgency on GM's part to get a handle on it, especially when this should be considered a safety issue from all the stories I've read.
i changed the battery and multiple fuses come to
find out it was the ground wire i had it replaced and
wham all set. Try that it only cost me $40 and the truck
sat for a month. Now i have a new problem it won't start
but it is trying to turn over not like before where nothing
worked except the interior lights. I changed the fuses but
no good i do here the fued pump kick in but it takes a few
seconds not sure if that's normal or not. Someone else said
they had simular problems and it was the onstar module that
kept the truck from starting. So i'm going to look into that.
Let me know how it goes.
